(*West is an option for DiracTrace and several other functions that deal with traces of Dirac matrices.The option applies only to the computation of $text{D}$-dimensional traces with an odd number of $gamma ^5$ in the Breitenlohner-Maison-t'Hooft-Veltman (BMHV) scheme.With West -> True (default setting), such traces are computed according to formula  (A.5) from Comp. Phys. Comm 77 (1993) 286-298, which is also known as West's formula. For more details, see the documentation for DiracTrace..*)
